SPECIFICATION forming part of Letters Patent No. 61,981, dated J' anuary 3, 1899.

Application tiled December 2l, 1896. Serial No. 616,377. (No model.)

To a/ZZ whom/ t may concern:

VER, a citizen of the United States, residing at New York, (Brooklym) county of Kings,

and State of NewYork, have invented certain new and useful Improvements in Printing- Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

machines; and the improvements consist in means whereby the mechanisms may be readily adjusted to the manipulation of sheets of varying lengths without the necessity of re- [5 setting the main working parts, thereby adapting it for the speedy making of short runs on different-sized sheets, all of which is particularly hereinafter fully described.

The illustrated embodiment of the invenzo tion is represented as follows: Figure 1 is a side elevation of such a machine in which the impression-cylinder O is equipped with means for producing and manipulating sheets of different lengths. Fig. 2 is a plan View of the same. Fig. 3 is a plan view taken on the section-line 3 of Fig. 1. Fig. tis apartial end elevation of Fig. 1, looking in the direction ofthe arrow 4 in Fig. 1. Fig. 5 is an enlarged side elevation of the compound adjustable drivingl 3o segment-wheel for causing and controlling the paper-feeding movement. Fig. 6 is a plan view thereof. Fig. 7 is a sectional plan thereof on the section-line 7 of Fig. 5. Fig. Sis an enlarged side elevation of the segment-wheel 3 5 shown in Fig. 5, but with the adjustable parts of said wheel in a dierent adj usted position. Fig. 9 is an enlarged sectional elevation on the section-line 9 of Fig. 10. Fig. 10 is an enlarged longitudinal sectional elevation of the 4o same on the section-line lO of Fig. 9. Fig. 1l is a sectional View on line 1l of Fig. 9. Fig. 12 is an enlarged end elevation of the impressioncylinder O as seen looking at the non-gear yend in the position of taking asheet. Fig.

13 is an enlarged sectional elevation of the impression-cylinder C similar to Fig. 9, but with the parts in the position reached when the sheet is being delivered. Fig. 14 is a partial side elevation of Fig. 13 as seen looking 5o in the direction of the arrow 14. Fig. 15 is an enlarged end elevation of the impression-cyl- This invention relates to bed and cylinder inder stop mechanism. Fig. 16 is an enlarged sectional plan view of one end of the impression-cylinder as seen 0n the section-line 16 of Fig. 15. Fig. 17 is a similar view as seen on section-line 17 of Fig. 15. Fig. 18 is a diagrammatic illustration of the means for operating the cutting mechanism.

Arrows point the directions in which the various views are seen.

This printing mechanism in its general characteristics is of ordinary construction and may be of any construction differing from that shown. As shown, the impression-cylinder C rotates in the usual bearings provided in the side frames, and its shaft 10 carries a toothed wheel 20, gearing with the bed-rack 2l, by which it is driven.

The traveling bedB is supported in a usual manner, as in ways or on rollers 51, and its reciprocation is produced by mechanism similar to that used in the Wharfdale printingmachine. Its driving-wheel 22, which is engaged with the rack 23 on the under side of the bed B, revolves on a shaft 24, and this shaft also carries on its opposite ends two spur-wheels G 7, (see Fig. 4,) that gear with short ixed longitudinal racks 25 26, these wheels (i 7 also having flanges 27 28 on their outer faces, which run upon longitudinal rails 219 30.

The shaft 24, carrying the large wheel 22 and the smaller ones 6 7, is journaled in the outer arms of a connecting-rod 32, which is reciprocated by means of a crank 31 on the driving-shaft 33, to which rod 32 it is pivoted, as is common in bed motions of this character and known as the railroad motion.

By the. use of the large and smaller spurwheels 22 and 6 7 the motion is multiplied, and a short crank movement produces the long reciprocation of the bed. By duplicating the wheel 22 and providing the bed with two corresponding racks greater stability may be given to the movements of the bed; but this might also be attained by making the wheel 22 and rack 23 of sufficiently greater width.

The impression-cylinder C in this illustrated machine is a stop-cylinder driven from the bed-rack, as we have seen. Its stop mechanism is illustrated in Figs. 15, 1G, and

IOO

17, and consists of means for arresting the saine at each revolution. The wheel 2O is free to turn on the shaft 10, except when locked thereto by the dog 8, which engages a recess in its inner periphery. (See Figs. 15 to 17.) This dog is pivoted to the cylinderhead and pressed to this duty by a springrod 46, and its locked condition is released by means of an arm 2, that is appropriately engaged by a cam 85, that is rocked on the shaft 10 (see Fig. 17) through a connectingrod 84, a rock-arm 185 (see Fig. 1) on shaft SG, and a rock-arm S7, that is actuated by a cam SS on the driving-shaft 33, this cam 8S being maintained in its normal position by a spring-arm 99. The outer end of this arm 2 when the latch is withdrawn by the cam to release the wheel 2O from the cylinder is so moved as to seat itself in ajaw 5, that is fixed to the side frame, its engagement with said jaw acting to suspend the movement of the cylinder.

The impression-cylinder C (shown enlarged in Figs. f) to 14) is, as illustrated, provided with the necessary openings in its shell for the accommodation of the mechanisms and carries a fixed cuttingblade 11, adjustable radially with respect to the periphery of the cylinder and having its cutting edge even therewith or slightly below said periphery. This radial adjustment of the cutting-blade is accomplished by means of slots in the blade and adjusting-screws passing through the same, as shown in Fig. 10, or by any other Well-known means. This cylinder is provided (see Figs. 9, 10, 12, and 13) with grippers 12, that coperate with nipping-arms 19, which grippers work through the openings in the cylinder, as shown. The surface of the cylinder between the openings is unbroken, and therefore forms a single impression-surface, each part of which is ready for instant cooperation with the form after the adjustment of the grippers by the means hereinafter referred to. Said gri ppers and nipping-arms are supported by a carrier G8, that is capable of swinging on the shaft 10 at one end of the cylinder and which has a member 69, that extends horizontally within the cylinder to support the gripper-shaft. For the purposes of this invention, as will be understood farther on, this carrier G8 is swung on the shaft 10 into the desired position to adj ust the grippers with respect to the size of the sheet being operated upon and held in the adjusted position by means of a suitable screw-clamp 34, which embraces a curved rib 42 and to which it may be fastened at the desired point; but other means for securing it in position may be used. The office of the carrier 68 is to transport bodily the gripper mechanism into and securely hold it in the required position with relation to the cutting-blade 11, or, in other words, secure it the proper distance from the cuttingblade to enable the web to be cut into sheets of the desired length and the gripping mechanism to properly operate upon such sheets.

The grippers are fast upon the shaft 1 and play in suitable openings in the shell of the cylinder, into which openings the nippingarms 19, that are fast to the member G9, project.

At the end of the gripper-shaft l that projects through the carrier 68 is fast a pinion 16, that is engaged on nearly opposite sides by segment-arms 17 and 14. The segment 17 is pivoted to the carrier G8, and its rockarm is attached to a spring-rod 52, that opcrates to maintain the grippers closed, and the opposite segment-arm 14, also pivoted to the carrier GS, is provided with a lateral stud 9, that engages a fixed cam 41, contact with which causes the segment 14 to rock, and thus rotate the gripper-shaft at proper times to cause the grippers to be opened at the sheetreleasing point and enable them to close at the sheet-receiving point to properly deliver a printed sheet and take a fresh sheet to be printed no matter what the length of the sheet may be. i.

For coperation with the cutting-blade 11 a vibrating cutting-blade 13 is provided. Its holder is fast to a rock-shaft 45, that is supported in brackets fast to the side frames. This holder is provided with an arm 37, that is attached to a spring-seated rod 3S, by which said blade is normally moved downwardly or into cutting position, and the shaft 45 is provided with a rock-arm 35, (see Fig. 18,) contacting with a cam 98, which is fast on the cylinder-shaft, (see Fig. 10,) by which the Vibration of the said cutting-blade is controlled, so that it is vibrated into cutting position, as in Fig. 18, for timely coperation with the passing blade 1l, the latter being adj usted to properly coact therewith in sweeping over its edge.

The paper web is fed forward (see Figs. l, 2, and 5 to 8) by means of a compound adj ustable driving segment-wheel 54 55, one member, 55, of which is fast upon the shaft 10 of the impression-cylinder and the other member, 54, of which is loose on the hub of the wheel 55. The segment 54 is provided with a clamping-screw 57, which extends through a slot 5S, with which the segmentwheel 54 is provided concentrically with its periphery, which clamping-screw 57 passes through this slot and enters a tapped hole near the rim. of the segment-Wheel 55, by which device the two members of the compound segment-wheel are clamped together as one. Each of these segment-wheels 55 54 is provided with an enlarged perimeter of a suitable extent, (illustrated in Fig. 5,) whereby said segment-Wheels operate as a cam of like extent when said segment-wheels are clamped together, as in Figs. 5 to S. This cam or driving surface may be extended, as is illustrated in Fig. 8, by loosening the clamping-screw 57 and swinging the loose segment-Wheel 54 the desired distance, which adjusted position may be secured by means of this clamping-screw 57, as shown in that IOC ITO

IZO

i lilfigure. In connection with this compound cam or paper-feeding segment-wheel there is a broad-faced pulley 56, (see Fig. 6,) one-half of which runs in frictional contact therewith, it being adjusted and held in such frictional contact by means of an adjusting-bolt 43, (see Fig. 1,) attached to the slide,which carries a stud on which the pulley 56 runs freely, and this pulley is made broad enough so that its inner portion may act as a band-pulley to receiveand propel a band 61, which, running over a pulley 62 on shaft 186, drives said shaft,which carries a pulley 162, fast thereon. The roll of paper 63 is rotated at a surface speed corresponding with that of the feeding movement imparted by said compound feeding segment-wheel by means of a contactpulley 65, which constantly rides on said roll and which pulley 65 is driven by means of a driving-band 64, that runs over it and the pulley 162. This pulley 65 is mounted in a swinging frame and rests by gravity in contact with the periphery of said roll of paper 63.

The sheet-delivery apparatus (best seen in Figs. 1, 3, and 13) consists of delivery-tapes 70, that extend from pulleys 71 near the cylinder to and return over pulleys 75. The pulleys 7l are loose on a shaft 92, that is hung in two arms 72 on studs supported by brackets depending from the side frames, each of said arms 72 being provided with a rock-arm 73, having a spring-seated rod 74, that constantly acts to throw forward the shaft 92 and the parts it carries. As the pulleys 71 thus pressed forward would otherwise enter into the cylinder-opening near the cutting-blade 11 when that opening is presented to them, the shaft 92 is provided with bearing-rollers 90, (see Fig. 14,) which bear on the unbroken part of the cylinder, and thus at that time prevents such movement of the pulleys 71 and at all times act to limit the forward position of the pulleys 71 and the tapes 70, carried by them, which are thus held nearly in contact with the lower periphery of the impressioncylinder. This shaft 92 also carries fast friction-rollers 91, which bear on the margins of the sheet and act with the cylinder C to drive the sheet onward to the tapes 70 when the grippers release it, and there is provided a stripping blade or arms 66, projecting sufficiently near the face of the cylinder to act as a means for diverting the sheet from the cylinder and guide the same onto said tapes. These tapes are driven at an appropriate speed by means of driving-bands 79 and 76, extending, respectively, from a pulley 82 on the shaft carrying the pinion 81,which meshes with the driving -wheel 80 on the drivingshaft 33, to a double pulley 77, and from double pulley 77 to a pulley 95.

In order to printashort sheet, the members 541 55 of the compound segment driving-wheel will be adjusted and set in the position shown in Fig. 5-that is to say, they will be adjusted with respect to each other and be looked together with the high parts of each coinciding,

compound driving segment-wheel 54 55 shall' represent the length of sheet desired to be manipulated, and which may then appear as is illustrated in Fig. 8, where the high part of this compound driving segment-wheel is shown as lengthened by such adjustment, which is secured by tightening the clampingscrew.

As the normal position of the grippers is that suited to the action upon the shortest sheet, comparing the relation of the grippers to the cutting-blade, Fig. 9, with the adjusted cam-surface in Fig. 5, it will be necessary when that raised cam or driving surface is eX- -tended, as in Fig. 8, to separate the grippers a longer distance from the said cutting-blade in order that an appropriate longer length of paper may be carried onward with the cylinder C before the cutting devices operate to sever the sheet length, and this is accomplished byswinging the carrier 68 into appropriate position and there securing the same. rIhe grippers will then operate as before (but at an earlier time) and properly close and seize the sheetat the receiving-point and open and release it at the delivery-point.

In the operation of this machine the web of paper extending from the rolled web 63 over the thin supporting end of the feedingtable 50 and resting motionless thereon will have its end seized by the grippers 12 when they arrive in their rotary travel in position to close upon the same, the high parts of the compound driving segment-wheel 54 55 contacting with the friction-pulley 56, the result being that as the grippers seize the end of the web said friction-wheel 56 will begin to revolve and through the belt 61 and connecting mechanisms appropriately drive the paperroll 63. The paper will then move onward at the velocity with which the impression-cylinder travels and the paper will be lapped onto the impression-cylinder to be printed. Vhen the predetermined sheets length has passed onward, the cutting-blade 13 will be vibrated at the appropriate time by the action of the cam 98, so that it will contact with the cutting-blade 11, the web being severed by the coaction of the two blades to form the predetermined length ,of sheet. The free part of each sheet, or tail end thereof, will be prevented from falling away from the cylinder by means of the curved guards 3, which depend from arms 4C. As soon as the web is severed the high part of the compound driving segment-wheel will have passed from con- IOO IIO

tact with the friction driving-pulley 5G and the paper will have ceased to move. lVhen the leading end of this sheet reaches the discharging-point, the grippers will be opened to release it, and the same will be propelled onward by the friction-rollers 91, and thus pass out onto the tapes for delivery in the usual manner, the stripper-blade 66 preventing the sheet from following the surface of the cylinder. It will be understood that at the time the bed is making its :return stroke the roll of paper will be motionless and the cylinder will be in a state of rest, caused by the seating of the arm 2 in the stationary jaw 5; also, that when the time therefor arrives the cam S5 will be rocked to release the arm 2 and permit the latch or dog 8 to engage the cylinder-wheel 20, and thus cause the paperfeeding cam to timely operate and the grippers and cutting devices to perform their functions.
